How to put commands into local database in c# visual studio for voice recognition
The easiest way is by using System. Speech. Recognition; here is described how to use it

Just change this code:

colors.Add(new string[] { "red", "green", "blue" });


And add results of a database query, for example, with Entity Framework and LINQ instead of new string [] {"red", "green", "blue"}. Something like this:

WordsToRecognize.Add(
context.MyTable
       .Where(x =&gt; x.Type == "type")
       .Select(x =&gt; new { x.Text }).ToList());


I'm not tested the code above, it just pseudocode
